Inspectors taking the first-ever inventory of flood control systems overseen by the federal government have found hundreds of structures at risk of failing and endangering people and property in 35 states. Levees deemed in unacceptable condition span the breadth of America. They are in every region, in cities and towns big and small. (AP Photo/Alex Brandon, File)
